为了生产高温无缺陷连铸坯,防止连铸坯出现裂纹,为连铸一连轧工艺创造必要的铸坯条件,日本钢管公司(NKK)自80年代初开始研制新型的气-水雾化喷嘴,用于二次冷却气,使之能均匀冷却并能自动控制冷却强度。该喷嘴由供水和供气管道,混合室、喷嘴头几部分组成。供水和供气管道中 In order to produce high temperature and defect-free billets and prevent the occurrence of cracks in the billets and to create the necessary billet conditions for continuous casting and continuous rolling processes, NKK has developed a new type of gas-water atomizing nozzles since the early 1980s, For secondary cooling gas, so that it can be evenly cooled and can automatically control the cooling intensity. The nozzle consists of water supply and gas supply pipe, mixing chamber, the first few nozzle components. Water supply and gas pipelines
